Line component comprises input port, dump valve, multiple high pressure nozzle, pipeline head and the contact plate for the protection of described multiple high pressure nozzle.This system is also included at least one high-pressure liquid line and electrical fitting of extending between supply trailer and hand-held coating tool.This system also comprises pressure line and sets the electronic controller (broadly, " valve closer ") of the duration that dump valve stays open between each period of energization of electronic switch.

In operation, to mix with the aqueous phase of mensuration from the liquid termiticide concentrate of doses of the mensuration of the container be housed on supply trailer and be supplied to coating tool by embedded spraying system.In another embodiment, termiticide solution is supplied to coating tool from storage tank or container and does not need embedded jet pump or device.In yet another embodiment, termiticide concentrate can be carried by operator and be housed in transportable container, and described container is formed in and/or remains on knapsack, shoulder leather sheath or shoulder belt, belt support frame, leg support frame and maybe can keep in other suitable devices of agricultural chemicals container.

Method and system as herein described utilizes high pressure to be ejected in the soil of underground by termiticide.High-pressure injection system described in literary composition and the known difference applying the liquid injection system of termiticide for soil purposes of at least some are, current industry standard liquid termiticide spraying system uses the pressure of 25 to 35psi to inject liquid in soil and by single injection tip or end.Example system described in literary composition is with from about 50psi to about 10, in the scope of 000psi, in another embodiment from about 1, with the pressure of about 4,000psi, termiticide solution is ejected in soil In yet another embodiment in the scope of 000psi to about 7,000psi.

In operation, coating tool is set at the desired pressure for applying termiticide.Then line component more specifically protects the contact plate of nozzle to be placed in the area of application of expectation by operator.Desired region can the wall of proximity structure thing or ground.Then operator presses down, with the axle of tool of compression on coating handle.This downward pressure makes the upper and lower of assembly axis draw close, thus actuating electronic switch.Switch will be opened dump valve temporarily and is allowed the termiticide solution of scheduled volume through high pressure nozzle and enter in soil.Switch will only allow one batch (i.e. termiticide solution of scheduled volume) through nozzle.Two of electronic switch isolation of components are allowed to carry out Resetting Switching by the pressure on release lever.Then coat operations person will make hand-held coating tool promote along wall or slide into next point of application and again press down on handle, thus repeat to spray termiticide solution in soil.Operator continues mobile hand-held coating tool and sprays termiticide until expect that the area of application is injected.In one example, expect that the area of application is the periphery of works, make termiticide barrier surround works completely and suppress termite to come works through this barrier thus.

In an alternative embodiment, electronic switch can to use finger or thumb press push button or switch by operator at it and to activated in T-handle part that part is positioned at instrument or near.In another embodiment, this instrument can comprise position marker, and when applying termiticide, position marker will apply such as foam, dust, powder, paint or dyestuff.Position marker will apply marker material to soil, to mark the position of contact plate during each coating.Permission operator is judged that where has carried out applying and mount board should be reorientated wherein to guarantee to carry out the continuously coating of termiticide around the periphery of works by visually.Marker also will contribute to the excessive or not enough coating preventing termiticide solution in the area of application.

High pressure coating tool as described herein and using method thereof have many advantages compared to known systems.Such as, the instrument described in literary composition can comprise embedded ejection assemblies, and this ejection assemblies eliminates to be needed to mix a large amount of termiticide solution, and decreases and to transport on public way or private industry or to process the relevant danger of a large amount of termiticide solution.The use of high-pressure injection instrument also eliminates termiticide solution being coated to the needs excavating (i.e. ditching) before in soil.Which reduce the view of the periphery of pending works and/or the destruction of natural vegetation.High-pressure injection instrument also reduce or eliminates and is pressed in soil to apply the needs of termiticide solution use applying device.High pressure tools also can carry out programming making each nozzle carry the termiticide solution of designated volume, and controls solution penetrate into the degree of depth in soil by controlling coating pressure.By control volume sum pressure, the coating volume of termiticide can reduce 25% to 80% of the coating of common liquid termiticide, thus provides cost savings and decrease water demand.This is in drier weather or particularly important at period of drought.High pressure tools has also significantly decreased the time needed for termiticide process around works.The minimizing of this time can in the scope between 40% and 80%.As a result, take the less time at the scene, and thereby reduce and to prepare to scene and to apply relevant labor cost.In addition, be designed to be close to when being ejected in soil by termiticide soil place the coating tool of nozzle and reduce operator or anyone is exposed to the risk of direct the area of application.

See accompanying drawing, Fig. 1 is the schematic diagram for termiticide being ejected into the high-pressure injection system 10 in soil according to exemplary embodiment of the present invention.Spraying system 10 comprises handhold portable coating tool 12 (broadly, " spraying equipment ") and termiticide fluid supply trailer 14 (broadly, " base unit ").Coating tool 12 is connected to trailer 14 via the pipeline 13 (such as flexible pipe) and at least one electrical fitting 15 limiting fluid passage.Pipeline 13 allows fluid (such as water and/or termiticide solution) to flow to coating tool 12 from trailer 14.Electrical fitting 15 for transmitting various control signal between coating tool 12 and trailer 14.

Fig. 2 is the front elevational schematic of handhold portable coating tool 12, and Fig. 3 is the schematic side view of coating tool 12.The pipeline head 16 that handhold portable coating tool 12 comprises handle 17 and is arranged on handle.Handle 17 comprises top 18 and bottom 19.The handle section 22 that top 18 comprises tubular section 20 and is attached on the upper end 24 of tubular section 20.As a result, the top 18 of handle 17 has the shape of T-shaped substantially.The bottom 19 of the tubulose of handle 17 customizes size and becomes for inserting in the tubular section 20 on top 18 of handle.When the bottom 19 of handle 17 inserts tubular section 20 of the top 18 of handle, top can move to the second compression position relative to bottom from the first extended position.The biased element that such as spring 26 and so on is set with by the top 18 of handle 17 towards its first extended position bias voltage.However, it should be understood that and can use any known biased element 26.Flange (not shown) or other suitable retainers can be set, to suppress the bottom 19 of handle 17 to be pulled from top 18 or otherwise to extract, guarantee that bottom keeps telescopically being attached to top thus.The lower end 28 of the bottom 19 of handle 17 is attached on inverted U-shaped attaching support 30.Pipeline head 16 is attached on attaching support 30 in its each end 32,34 pivotally via a pair pivotal pin 36.

Pipeline head 16 comprises at least one internal path, to distribute termiticide to the multiple high pressure nozzles 38 be communicated with internal path fluid.As shown in Figure 3, illustrated pipeline head 16 comprises two main internal paths 40,42 and the line passing 44 being connected main internal path.Can imagine, pipeline head 16 can comprise the high pressure nozzle 38 of any amount.Such as, the pipeline head 16 of exemplary embodiment has the matrix of 6 high pressure nozzles 38, and wherein each nozzle is equidistant each other substantially.In one embodiment, each high pressure nozzle 38 has from the aperture in the scope of about 0.002 inch to about 0.01 inch.

Again see Fig. 2, contact plate 50 is attached on the bottom surface 52 of pipeline head 16, to protect high pressure nozzle 38.In the illustrated embodiment in which, contact plate 50 comprises multiple opening 54, and wherein each opening is aimed at substantially to the corresponding nozzle in multiple high pressure nozzle 38.As a result, high pressure nozzle 38 is spaced apart with soil and therefore directly can not contact with soil by contact plate 50.In addition, contact plate 50 block or be otherwise blocked in the injection period of termiticide may the soil of " being kicked up (kicked-up) ", rock and/or other chips.Contact plate 50 comprises circular edge to be conducive to the slip of instrument 12.Contact plate 50 can be made up of any suitable material such as metal and/or plastics.

The size and dimension of pipeline head 16 can be selected based on the special-purpose of plan use instrument 12.In one embodiment, pipeline head 16 has the shape of high-aspect-ratio, and such as high pressure nozzle 38 becomes a line orthoscopic ground to arrange as shown in Figure 4.In another embodiment, pipeline head 16 has arc as shown in Figure 5.The pipeline head 16 of arc can be used for being engaged in around circular edge such as to be set around.Can imagine, pipeline head 16 can be interchangeable.That is the operator of instrument 12 optionally changes pipeline head 16.Also can imagine, other conveying plants available (such as bar spraycan) replace pipeline head 16, for the supply of low-pressure delivery termiticide.These low-pressure delivery unit are used in the region of not too applicable high-pressure injection.

The weight of pipeline head 16 may be selected to and makes the quality of pipeline head 16 contribute to, between multiple high pressure nozzle 38 expulsive stage, instrument 12 is being remained on appropriate location, and can cause the burden by operator's manual positioning and Move tool necessarily.Generally speaking, the quality of pipeline head 16 is lighter, and operator is larger with power instrument 12 being remained on appropriate location from being applied to handle 17 between high pressure nozzle 38 expulsive stage at termiticide.

As shown in Figure 2, dump valve 56 to be attached on pipeline head 16 and with the supply fluid communication of the internal path 40,42,44 in pipeline head and termiticide.More specifically, one end of dump valve 56 is connected to high input voltage port 58 and the other end of dump valve is connected to flexible pipe 13.Dump valve 56 can move between an open position and a closed.When dump valve is in its closed position, termiticide is inhibit to flow to internal path 40,42,44 pipeline head via high input voltage port 58 from the supply of termiticide via flexible pipe 13.When dump valve 56 is opened, termiticide solution flows through flexible pipe 13 from the source of supply of termiticide at elevated pressures and flows into input port 58.Pressurization termiticide is from the internal path 40,42,44 of input port 58 inflow pipe the end of a thread 16 and flow through high pressure nozzle 38, and termiticide is ejected into soil from described high pressure nozzle 38.In one embodiment, termiticide is pressurized to the pressure of about 25psi to about 10,000psi, in another embodiment, be pressurized to the pressure from about 1,000psi to about 7,000psi, and In yet another embodiment, be pressurized to the pressure of about 4,000psi.

In one suitable embodiment, dump valve 56 can operate fast enough to allow dump valve 56 in the time parameter expected, open and close the solenoid operated lift valve allowed based on the correct soil permeability degree of depth of pressure when using and the volume for the correct termiticide solution of special-purpose.Although can use hydraulic actuated valve, the size of this valve and weight restriction may limit the practicality of hand-held coating tool 12.

In the embodiment that another is suitable, pipeline head 16 can have the dump valve 56 relevant to each high pressure nozzle 38, makes to guarantee that termiticide fluid crosses over being uniformly distributed of multiple high pressure nozzle 38.Although can obtain in rational parameter simply by the suitable customization size of internal path 40,42,44 and discharge balance, if but need and prove spending reasonably words, multiple dump valve 56 can be used, make to supply the pressurization termiticide solution held in the supplying flexible pipe of each dump valve 56 and can ensure that each high pressure nozzle 38 can obtain enough termiticide solution.But, such a configuration increases the complexity of system 10, because controller must activate multiple dump valve 56 in response to single actuation, namely, the electric power adding wiring amount and control needed for each valve, but electricity needs is offset by using less dump valve 56.
